Warning: Sensor signal to low

Not enough signal light reaches the detector of the device.

Please Check:

Is the respective sensor connected to the correct channel of the device?
For contactless sensors: Does the bare optical fiber face the sensor spot/ foil/ dispersed nanoprobes?

If yes:

• Fiber sensor: The tip/ fiber might be broken or the optical sensor is bleached. In both cases, the sensor needs to be replaced.
• Contactless sensor: Reduce distance between the optical fiber and the sensor spot/ foil
• Nanoparticles: Reduce distance between the optical fiber and the dispersed Nanoparticles and/ or increase the nanoprobe concentration
